Officials are probing how a 51-year-old highway bridge came to collapse in the Italian port city of Genoa yesterday, killing at least 26 people and injuring 16 others as it sent dozens of vehicles tumbling into a heap of concrete and twisted steel.

Deception Bay murders a case of ‘mistaken identity', police say

A Queensland mother and her brother were allegedly murdered in a case of mistaken identity, detectives have said.

April and Ian Bailey were found dead inside their fire-ravaged home at Deception Bay, north of Brisbane, on May 28, 2004.

Detective Inspector Damien Hansen claimed the siblings, who were allegedly killed in front of April's then five-year-old daughter Violet, were targeted because of the actions of another woman called April from the same area.

“April had come into possession of a large quantity of drugs," Insp. Hansen told The Courier-Mail.

“But it was not April Bailey - they've got the wrong April.

“It's not even the wrong place at the wrong time. They were targeted through just an unfortunate set of circumstances,” he said.

Danielle Lee Fels , 34, was arrested last week over the incident as police made a fresh appeal for information, suspecting up to four people were involved in the crime.
